[0 all whom it may concern:

Be it known that I, lVILLIAM S. VAN SANT, a citizen of the United States, residing at Fruitvale, in the county of Alameda and State of California, have invented a new and useful Improvement in Paper- Cone-l/Vrapping Machines and the Product Obtained Thereby, of which the following is a specification.

This invention relates to a machine for the manufacture of paper containers, and especially to a machine which is adapted to form and wrap cone-shaped containers.

The invention also relates to the product obtained, to-wit, a cone-shaped paper container folded .or wrapped in such a manner that a water or liquid tight container is pro duced.

One of the objects of the present invention is to provide a simple, substantial and cheaply manufactured paperwrapping and forming machine which is especially adapted for forming and wrapping cone-shaped containers, and simultaneously adapted to trim the paper or stock from which the container is formed so as to produce an even annular edge around the upper open end of the cone.

Another object of the invention is to provide a wrapping or forming machine of the character described by which a water or liquid tight joint or fold may be formed at the lower or pointed end of a paper cone,

'said fold also serving to reinforce and strengthen the pointed end of the cone.

Another object of the invention is to provide ayieldable paper feeding table for the reception of the stock or sheets from which the cones are formed, and to so position the feeding table that the sheets may be easily delivered one by one to the wrapping mechanism.

Another object of the invention is to provide means for rotating the wrapping mechanism while each cone is formed, and in conjunction therewith to provide means for ejecting the cones one by one when formed.

Further objects will hereinafter appear.

The invention consists of the parts and the construction, combination and arrangement of parts as hereinafter more fully described and claimed, having reference to the accompanying drawings, in which- F 1g. 1 is a plan view of the cone forming and wrapping machine.

Fig. 2 is a front view of the wrapping cone.

Referring to the drawings in detail, A indicates a base member of suitable construction upon which is secured a pair of bearing members 2 and 3. Journalled in said hearing members is a hollow shaft 4:, and secured on said shaft is a cone shaped wrap-- ping member 5. Also secured on the shaft or formed integral with the cone, as indicated at 6, is a head member. This member is spaced with relation to the base portion of the cone and an annular channel 7 is in this manner formed for the reception of a I trimming knife 8, the function of which will hereinafter be described. Extending through the hollow shaft 4 and the cone member 5, and adapted to turn in unison with the shaft is a rod 9. Secured on the rod is a collar 10, and interposed between the collar and the head member 6 is a spring 11. Formed on one end of the rod 9 is a striking plate 12, and secured on the outer end of the rod is a pointed section 14, which forms a part of the main wrapping cone 5,

that is the cone 5 is made in two sect-ions as indicated at 5 and 14, the section 5 representing the main portion of the cone, and the section 14, the pointed end or the apex of the cone The section 14 is provided for the purpose of ejecting paper cones when completed. It is therefore capable of separation or longitudinal movement wit-h relation to the main cone section 5, by means of the rod 9 and the striking plate 12, that is pressure exerted on the plate 12 will impart longitudinal movement to the rod 9 and the section 14 carried thereby, this longitudinal movement being sufficient to eject the cones one by one when completed, the spring 11 servingthe function of returning the rod 9 and the section 14 to normal position as shown in Figs. 1 and 5. The head member 6 and the cone sections 5 and 14 are channeled as indicated at 15, the channels formed in the respective sections being aligned to form a continuous channel for the reception of one edge of the paper blank as shown in Fig. 1 when the wrapping operation is to be started. With the paper inserted in the channel, it is only necessary to turn the cone approximately two revolutions. This is accomplished 1n the present instance by manual operation through the medium of a hand crank 16. Turning movement imparted to the cone causes the paper to wrap itself about the cone and as a rectangularblank is employed, it is obvious that the upper edge will necessarily have to be trimmed to form a smooth annular edge. This is accomlished by providing the trimming knife 8. his knife is supported by an arm 17,

hingedly secured to the base plate A as at half of each sheet having paste applied thereto in any suitable manner'before delivcry to the feeding table. The .feeding table is hingedly secured at one side as at 19 to the base plate and the opposite side is resili ently supported by means of a spring 20. This side. of the feeding table is extended as at 21 to form a handle or projection, by

which the table may be depressed, and theupper end of the table or that passing under neath the wrapping cone is slightly concave as at 22, (see Fig. 4.) to frictionally engage the exterior surface of the wrapping cone, that is a paper blank having paste applied thereto, as shown at 23, is placed on the table in such a manner that one edge thereof enters the channel 15 formed in the wrap ping cone. Rotary-movement is then transmitted to the cone by means of the hand crank 16. In this manner causing the paper to wrap itself about the cone. The concave portion of the. table, indicated at 22, frictionally engages the surface of the cone and thereby causes the paper to be tightly wrapped about the same. The trimming knife or blade 8 simultaneously engages the outer uneven edge of the paper blank and proper trimming thereof is in this manner accomplished. It requires approximately two revolutions to complete the operation and'as one-half of the sheet or blank has paste appliedthereto, it is obvious that tainer which is not only decidedly stronger than paper cones. heretofore produced, but also liquid tight. These results are obtained in the. following manner:

By referring to Fig. 1, it will be seen that the paper blank when inserted in the channel 15 is a little longer than twice the length of the wrap-ping cone, that is 'the cone merely reaches the dotted line indicated at 25, the center line of the blank being indicated at'26. The paper when wrapped is therefore started slightly off center and caiises a lateral fold 27 tobe shown in Figs. 6 and 10. This fold. not only reinforces and strengthens the point of the cone, but it also produces a .water tight joint,

a feature. which is decidedly desirable as it permits the paper cones to be employed for a variety of uses, for instance as drinking produced as L cups or containers for ice cream, and a great v variety of other articles.

The machine here shown is decidedly simpie and substantial in construction. The feeding table is arranged on an angle with.

relation to the longitudinal axis of the wrap-.

ping cone, the angular relation being equal to the inclined exterior surface of the wrapping cone and running parallel therewith. Thepaper blanks delivered thereto, one by one, are therefore readily inserted in the feeding slot 15 of the cone and are adjusted and held in position by means .of a guide 28. The paste may be applied in any suitable manner and as the p-aperis snugly forced against the exterior surface of the wrapping cone by the feed table extension 22, it can be seen that a uniform and perfect product will be obtained. w The trimming knife employed may be an ordinary safety razor blade or the like. This blade may be readily removed by detaching the spring 19 and swinging the arm 17 about the hinge support 18. No time should therefore be lost when the trimming blade becomes dull as a new and sharp blade may be readily inserted.

While the present machine shown is equipped with a hand crank, it is obvious that a power drive may be employed. Similarly that various changes in design and construction may be resorted to within the scope of the appended claims, also that the materials and finish of the several parts employed may be such as the experience and judgment of the manufacturer may dictate or varying uses may demand.

Having thus described my invention, what I claim and desire to secure by Letters Patent is- 1. In a wrapping machine of the character described a shaft, a cone-shaped member carried thereby said cone shaped memher having a channel formed therein which extends from the apex to the base of the cone, means for rotating the shaft and cone carried thereb an annular groove formed in the cone a jacent the base thereof, and a trimming knife projecting therein.
